Abstract
The utility model relates to an improvement of a flow equalizer for the air blower and air return fan of a combined air-conditioner, which is characterized in that the flow equalizer consists of folded plates with a diffusion angle, wherein the folded plates are arranged in a shape like a Chinese character 'hui'at intervals. The folded plate type diffusion structure has a good flow equalization effect, and the wind speed uniformity on the cross section is above 90 percent, thereby greatly improving the heat exchange efficiency of the heat exchanger and reducing the wind resistance which is controlled at about 30 Pa. With the improvement of the heat exchange efficiency and the reduction of the wind resistance, the energy-saving and consumption-reducing effect of the air-conditioner is obvious, which facilitates the significant reduction of the air-conditioner operating fees. Based on tests, the energy consumption can be reduced by about 5 percent compared with the unit with the identical power. As the wind resistance is low, the damage to the flow equalizer is reduced, and the service life of the flow equalizer is obviously prolonged. The utility model completely solves the problemof poor air flow equalization existing for a long time in the air-conditioner industry.
Description
Technical field
Utility model be about combined type air conditioner is given, the improvement of return fan current equalizer, relate in particular to a kind of current-sharing better effects if, and the little combined type air conditioner of windage send, the return fan current equalizer.
Background technology
Combined type air conditioner, usually air-conditioning unit cross section is roomy, for example big reached at 4*4 rice, and pressure fan bore maximum also only is a 1.2*1.2 rice, little blower fan discharge area, with big airduct cross section, add to be subjected to length restriction can not be added with long reducing changeover portion again, thereby very easily cause air intake on cross section, not to be evenly distributed.Air-supply can influence filter efficiency in airduct cross section uneven distribution, and filters refrigerating efficiency, and over against the blower fan discharge area, directly blown by high-pressure blast, impacts greatly, and filter damages easily.Prior art for this reason, proposition is provided with the metal perforated plate current equalizer before the blower fan air outlet, utilize the orifice plate planar diffusion to reach current-sharing, yet metal perforated plate current equalizer, meeting is in to a certain degree balanced ventilation, but the section face wind speed uniformity is still lower, has only about 60%, also do not reach national standard 80% above requirement, thereby actual current-sharing DeGrain; Secondly, metal perforated plate current equalizer windage is higher, reaches about 130Pa, has increased the unit power consumption, has increased energy resource consumption.Besides, orifice plate current equalizer windage is higher, also easily causes the damage of current equalizer.Therefore still having is worth improved place.
The utility model content
The utility model purpose is to overcome the deficiency of above-mentioned prior art, and a kind of current-sharing better effects if is provided, and the little combined type air conditioner of windage send, the return fan current equalizer.
The utility model purpose realizes that main the improvement is to change the orifice plate current equalizer into band angle of flare flap alternate Back Word combining structure, thereby overcomes above-mentioned prior art, realizes the utility model purpose.Specifically, the utility model combined type air conditioner send, the return fan current equalizer, it is characterized in that the flap of said current equalizer by the band angle of flare, and is alternate with three-back-shaped combination composition.
The flap of band angle of flare, serve as reasons short straight section and Eight characters limit of a kind of better form constitutes, the straight section wind-guiding, the diffusion current-sharing of Eight characters limit, the angle of flare that its Eight characters limit forms is preferably the 200-250 degree through test, specifically can determine according to fan outlet area and the test of airduct cross-sectional sizes, for example air-conditioning unit cross section is big, and angle of flare is suitable big.Band angle of flare flap spacing, test being preferably spacing 80-150mm, and spacing is too small can to increase windage, helps reducing windage though spacing is excessive, and the current-sharing effect can be affected.By adjusting each flap angle of flare size, and adjacent spacing, reach and improve the air-supply uniformity and reduce windage.Current equalizer thickness is preferably 120-150mm, and thickness increases can increase manufacturing cost, and thickness is too small can to influence the current-sharing effect.
The utility model current equalizer, same unit, its flap blade angle of flare can be identical, also can be different, for example angle is reduced gradually by middle mind-set edge, and these all can be determined according to airduct cross sectional shape, size test.
The utility model combined type air conditioner send, the return fan current equalizer, with respect to prior art, because the flow deflector that adopts the band angle of flare is by the alternate composition current equalizer of putting of Back Word, tabs formula diffusion structure, current-sharing is effective, wind speed is even at the airduct total cross-section, and the sectional wind velocity uniformity has significantly improved heat exchanger (also claiming surface cooler) heat exchange efficiency height more than 90%, and windage reduces greatly, windage is controlled at about 30Pa, and heat exchange efficiency improves and windage reduces, and the air conditioner energy saving consumption reduction obviously, help the remarkable reduction of operation of air conditioner expense, through experimental test, the equal-wattage unit can cut down the consumption of energy about 5%.The current equalizer windage is little, has also reduced the infringement to current equalizer, can significantly improve the service life of current equalizer.Thoroughly solved blow for a long time problem of current-sharing weak effect of puzzlement air conditioner industry.
Below in conjunction with a specific embodiment; utility model is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the technical scheme qualification total to utility model, some do not depart from the unsubstantiality of utility model design and change In the view of the technical staff; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
Description of drawings
Fig. 1 is for the utility model combined type air conditioner send, return fan current equalizer structural representation.
Fig. 2 is Fig. 1 side-looking structural representation.
The specific embodiment
Embodiment: referring to accompanying drawing, the utility model combined type air conditioner send, the return fan current equalizer, being included in square installs in the frame 1, by the three-back-shaped alternate flap flow deflector 2 composition current equalizers that angle of flare is 230 degree that are provided with, flap spacing 100mm, thickness 120mm, four jiaos have the connector 4 of installation, and wherein flow deflector 2 is formed flap by straight section and Eight characters limit.Be air inlet 5 by flow deflector straight section end during placement, Eight characters limit end is an air outlet 3, is fixed in the blower fan front, forms current equalizer.
To those skilled in the art; under this patent design and specific embodiment enlightenment; some distortion that can directly derive or associate from this patent disclosure and general knowledge; for example those of ordinary skills will recognize also and can adopt additive method; or the substituting of known technology commonly used in the prior art; and the mutual various combination between feature; for example according to the airduct cross sectional shape; form with the airduct cross section current equalizer identical shaped; or the like unsubstantiality change, can be employed equally, can both realize and basic identical function of the foregoing description and effect; launch for example no longer one by one to describe in detail, all belong to this patent protection domain.
Be easy description, utility model is said to be sent, return fan, comprises pressure fan and return fan.
